Outline
In order to enhance the efficiency and rationality of water resources allocation in Minjiang River, a water allocation index system including the monitoring rate of water intake, the rate of water quality of control sections meeting the standards and the early warning of discharge was established from the perspective of water resources management and assessment effectiveness. And then the quantitative calculation of the water intake of each water-taking city and the importance of each index were carried out by the comprehensive weighting method which combines the subjective and objective factors. The results show that the results of water intake distribution are consistent with the actual of water diversion, and the demand of water resources in Chengdu, Meishan and other cities in the middle reaches of Minjiang River is large, which can provide a basis for water resources regulation and water rights trading in Minjiang River. The supervision rate of water intake and the rate of water quality of control section are of great weight among the 6 new indexes, which provides an idea for constructing a new index system of water allocation. The results of water diversion take into account both the health of rivers and the requirements of water environment, and try to directly link the benefits of water resources management with water diversion, which can provide reference for actual water diversion, and urges each area to have the emphasis to continue to do well the water resources management and the appraisal related work.
